Shingles is a common and painful disease, it can result in long-term pain and in rare cases can even be fatal. It is recommended that all adults in the UK are offered the shingles vaccine on their 70th birthday. Uptake of the shingles vaccine is suboptimal, therefore strategies to improve uptake are needed.
Routine reporting of the shingles vaccine suggests that uptake is greater during the influenza season, and it is assumed this is due to it being offered at the same time as the annual flu vaccine. A new vaccine for shingles has been recommended since 2021, a recombinant herpes zoster vaccination.
Up until May 2023 concomitant administration of RZV with either adjuvanted or COVID-19 vaccine (C19) was not recommended due to concern about misattribution of side-effects and limited experience with COVID-19 vaccines. The policy was updated in May 2023 to allow co-administration of COVID-19 vaccines with any vaccine. This was based on recent evidence supporting the acceptable safety profile of a COVID-19 vaccine with RZV and to improve timely protection and uptake. There is still a need however for safety data with co-administration of second dose of RZV as the adverse event profile differs between the doses and there is a lack of published data on the safety and immunogenicity of RZV and adjuvanted flu vaccine.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

01 Oct 2023 28 Feb 2025

Participants will be required to attend six study appointments over a period of 5 months at their nearest participating site. They will be randomly allocated into one of five groups, and they do not know which group they are in. Participants will be required to provide blood samples at study visits, and complete an e-diary in-between visits.

Below are the locations for where you can take part in the trial. Please note that not all sites may be open.

The potential benefits will be protection against COVID-19, Herpes zoster and influenza. However, some participants may already be up to date with their COVID-19 and flu vaccines, and the additional COVID-19 and flu vaccine as part of the study would not offer them additional protection.
Localised bruising and discomfort can occur at the site of blood sampling. Infrequently fainting may occur. The total volume of blood drawn over a 6-week period will be approximately 260 ml (blood volumes may vary slightly for participants at different investigator sites due to the use of different volume vacutainers, following local Trust procedures). This should not compromise these otherwise healthy volunteers, as these volumes are within the limits of 470 ml every 3–4 months for blood donations to the National Blood Transfusion Service.
Allergic reactions from mild to severe may occur in response to any constituent of a medicinal product’s preparation. Anaphylaxis is extremely rare (about 1 in 1,000,000 vaccine doses) but can occur in response to any vaccine or medication. People very often have tenderness, pain, warmth, redness, itching, swelling or bruising or less commonly have a small lump in their arm where they have been vaccinated. After vaccination it is common to experience the following side effects for all vaccines: fatigue, joint aches, muscle aches, headaches, feeling sick/nauseated/vomiting or diarrhea, flu-like symptoms, such as high temperature, sore throat, runny nose, cough and chills, feeling unwell. With the shingles vaccine 1 in 10 people may experience these common side effects that are severe enough to interfere with their daily activities. They usually last for less than a week (more commonly 24-48 hours after vaccination). Other less common side effects are: abdominal pain, feeling dizzy, excessive sweating, itching skin or rash, decreased appetite, and swollen lymph nodes.
